Lower and upper estimates on the excitation threshold for breathers in DNLS lattices
(2009)
We propose analytical lower and upper estimates on the excitation threshold for breathers (in the form of spatially localized and time periodic solutions) in discrete nonlinear Schrödinger (DNLS) lattices with power ...

Solitons in one-dimensional nonlinear Schrödinger lattices with a local inhomogeneity
(2008)
In this paper we analyze the existence, stability, dynamical formation, and mobility properties of localized solutions in a one-dimensional system described by the discrete nonlinear Schrödinger equation with a linear point ...
